Question about Polaroid TLX-01511C LCD TV
I have a Polaroid TLX-01511C, it will come on and stay on for a few seconds then the screen goes dark but if you look real close you can see the screen.
I was told that it is the LED inverter board. If so is this the board that is part of the screen??
If the screen is still glowing, then you may have either dead T-CON board or the main board. Dead backlight inverter board will not get any glow on the front or the back of the LCD panel.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there are some troubleshoot you will have to do to find out the causes of the problem you are having.

You need to list what pins on the Board need the voltage
3.3 volt 12volt and a 24 volt and 5 volt need the schematic
all caps are good
